Question

How is lava formed?​

Answer 1

Answer:

It is created deep beneath Earth's surface (often 100 miles or more underground), where temperatures get hot enough to melt rock. ... Eventually, some magma makes its way to Earth's surface and escapes via a volcanic eruption. When magma erupts onto Earth's surface and begins to flow, scientists then call it lava.

Answer 2

Explanation:

Lava forms when magma erupts from a volcano. As pressure is released gases, dissolved in the magma, bubble out so the composition of lava changes. Most lava flows are formed by the eruption of hot (around 1200oC) basalt magma
